Photosynthesis & Pigments

Front

What is photosynthesis?

Back

The process of using sunlight to create sugars.

Front

What are reactants in a chemical reaction?

Back

Molecules that go into a reaction.

Front

Which pigment is least likely to be reflected from Chlorophyll A?

Back

Blue.

Front

How does a broad leaf fit its function?

Back

It has more surface area to catch more sunlight.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll absorbs light energy, primarily from the blue and red wavelengths.

Front

What are carotenoids?

Back

Pigments that absorb light in different wavelengths than chlorophyll, aiding in photosynthesis.

Front

Why do plants have different pigments?

Back

To absorb a wider range of light wavelengths for photosynthesis.

Front

What is the equation for photosynthesis?

Back

6CO2 + 6H2O + light energy -> C6H12O6 + 6O2.

Front

What is the significance of the light-dependent reactions?

Back

They convert solar energy into chemical energy (ATP and NADPH) and produce oxygen.

Front

What happens during the Calvin cycle?

Back

Carbon dioxide is fixed into glucose using ATP and NADPH produced in the light-dependent reactions.
